NOTES:
1. When use VCC1 > VCC2, contacts due to some points or restrictions to be checked.
2. This pin function in M16C/62PT cannot be used.
3. Ask the oscillator maker the oscillation characteristic.

Description
Main clock
input
XIN I VCC1 I/O pins for the main clock generation circuit. Connect a ceramic
resonator or crystal oscillator between XIN and XOUT
(3)
. To use
the external clock, input the clock from XIN and leave XOUT open.
Main clock
output
XOUT O VCC1
Sub clock input XCIN I VCC1 I/O pins for a sub clock oscillation circuit. Connect a crystal
oscillator between XCIN and XCOUT
(3)
. To use the external clock,
input the clock from XCIN and leave XCOUT open.
Sub clock
output
XCOUT O VCC1
BCLK output
(2)
BCLK O VCC2 Outputs the BCLK signal.
Clock output CLKOUT O VCC2 The clock of the same cycle as fC, f8, or f32 is outputted.
